10 Claims. (01.155-194) My invention relates to furniture and .is generally directed: towards providing articles of this nature in which the-parts are retained together.

without the use of'glue, small screws,'nai1s, 0r

similar fastening materials and devices now common in the industry.

One object ofmy invention is to devise an article of furniture which is constituted by the assembly of a plurality of small pieces whose relation to each other is such that, under load conditions, they may give slightly, so that the article is characterized by a certain degree of flexibility which, in some kinds of furniture such as'chairs and the like, is reflected'in an improved standard ofcomfort,

A further object. is to provide an article of the character described in which the several parts are firmly tied together to achieve maximum strength with a minimum of weight, while also permitting the attainment of a desirable attractiveness in appearance.

Afurther object is to devise an article of furniture which may be quickly and easily assembled by unskilled labor, and which is capable of being shipped in a knocked down condition for later assembly.

For purpose of illustration, my invention will be described as; applied to a chair, as indicating the essential featuresthereof, but no restrictive interpretation is to be placed on the invention ior that reason, as the details of construction are readilyapplicable to other types of furniture, suchas lounges, tables, dressers and other varieties. v i 1 These and further objects of my invention will be set forth in the following specification, reference being had to the accompanying drawings, and the novel means by which'said objects are effectuated will be definitely pointed out in the claims.

In the drawings;

. Fig, 3 is a side, sectional elevation of the chair.

Fig. 4 is an enlarged sectional elevation of a portion of the chair, showing the manner of assembling the seat to the front legs.

Fig.5 is a sectional elevation showing a modifled-arrangement of attaching the ends of the brace members to either thefront or back legs.

Referring to Fig. 1, the numeral 10 designates M REIS-SUEDA my improved article of furniture, fashioned i'm'; purpose of illustration as a chair, and which comprises front legs 11, rear legs '12, braces 13 extending between indicated. pairs of said legs, a" seat 14, back standards 15', a back rest 16 extending between said standards, armrests 17, supports 18 for said rests. [These several parts are constructed and assembled together in manner which will now be described.

Generally speaking, the front and back legs, back standards, and arm rest supports are fabricated from a number of smaller pieces which are assembled together in a certain definite manner. Considering a front leg 11 for purpose of example, said leg comprises a rod 19 whichis threaded at its opposite ends and on which are mounted the several pieces which create the -ex-- ternal appearance of the leg and also sustain the load imposed thereon. A nut 20 is first threaded on the lower end of the rod 19, after which'the other pieces which constitute the'leg are successively strung on the rod 19 from the opposite, or Fig. 3. Specifically, the nut 20 having been positioned, a special washer 21 is slipped on said rod and moved downwardly into engagement with said nut. The washer 21 is preferably formed as a cup-shaped stamping with an intermediate, horizontal, annular portion 22 which is'deflned by- .an outer shoulder 23 and an inner shoulder 24, said shoulders extending in opposite direction from the annular portion 22. As mounted in Fig. 3, the washer. 21 seats on the nut20 in in verted position, with the under side of-the. an-

:nular portion '22 contacting with the upper side of the nut 20. A simple tubular sleeve 25 of predetermined length is then slipped on the rod 19 and moved downwardly until the end thereof rests on the upper side of the annular portion 22, after which a second washer 21 is placed on the rod 19, but in a reversed position from that indicated for the lower washer, and with the upper end of the sleeve 25 contacting with the under, or outer, side of the annular portion 22 of the second washer 21;

upper end, thereof, as viewed in A special washer 26 having a centrally disposed aperture 27 is then slipped over the rod 19 and said washer is also preferably formed as a in Fig. 3, and with said base resting against the inner, or upper, side of the annular portion 22 of the second washer21. As shown in Fig. 3, the peripheral wall 29 is substantially in alignment with the wall of the sleeve 25, this construction being adapted for a purpose hereinafter explained. One end of the brace 13 having an aperture 31 is then dropped on the rod 19 and moved downwardly until the underside thereof seats on the upper side of the annular flange 30 on the washer 26. Thereafter, in succession, washers 26 and 21 are placed on the rod 19in reversed positions from those indicated for the washers 26 and 21 immediately below the brace 13 and they are moved downwardly until the annular flange of the washer 26 rests on the upper side of the brace 13 and the under, or inner, side of the annular portion of the washer 21 rests on the base of the washer 26. The washers 21 comprise an annular hood portion 32 which defines their largest diameter and, as shown in Fig. 3, these hood portions closely approach the opposite surfaces of the brace 13 and completely conceal the washer 26, thereby improving the appearance of the chair.

A second sleeve 25 is then placed on the rod 19 and moved downwardly until its lower end abuts against the outer, orupper, side of the annular portion 22 of the adjacent washer 21. The brace 13 which extends between the front legs 11 and its companion washers 21 and 26 are then mounted on the rod 19 in the same manner as just described for the brace member 13 which extends between a front and a back leg, after which a third tubular sleeve 25 is positioned on the rod 19, followed by successive inverted positionings of the washers 21 and 26. The forward end of the seat 14 which includes a hole 33 is then placed on the rod 19 and moved downwardly until its underside rests against the upper side of the annular flange 30 on that washer 26 which has been last placed in position. A plain washer 34 is then slipped on the rod 19, followed by a plain nut 35 which, when tightened against the lower nut 20 securely positions the several sleeves,

washers, and brace members in abutting relation on the rod 19. A washer 21 is then placed on the upper end of the rod 19 as a concealing member for the washer 34 and nut 35, after which a finishing ball nutv 36 is threaded on the upper end 'of the rod 19 and a similar nut 36 is placed on the lower end to provide a smooth, sliding contact with the floor surface, thus completing the assembly of one of the front legs.

Each of the rear legs is assembled in a manner identical with that heretofore described for a front leg, the only changes occurring where it is necessary to establish a joint between two brace members 13 and the rear leg, as shown in Fig. 3, and this step is accomplished merely by placing the endsof the brace members in overlapping position. A secondchange occurs where it is unnecessary to provide for a joint connection for bular sleeves 25. In such a case, a single washer 21 is interposedbetween the sleeves 25, with the inner shoulder 24 extending upwardly within the upper sleeve 25 and the outer shoulder 23 depending externally of the upper end of the lower sleeve 25, the opposed end edges of said sleeve contacting with the opposite sides of the annularportion 22 of the washer.

As a simplification of the construction, it is contemplated that the back standards 15 will be constituted by an upward continuation of the back legs 12 and for this purpose, a'longer, central rod 37 is employed in the construction of the back legs, but otherwise this last-named rod is identical with the rod 19 and is threaded at its opposite ends. The connection of the rear edge of the seat 14 with the rod 3'7 is made in the same manner as that indicated for the front edge of said seat with the rod 19, except that on the upper side of said seat, washers 26 and 21 are successively placed on the rod 37 in reverse position-to those indicated for the same washers on the underside of said seat. A sleeve 25 is then placed on the rod 37, followed by a placing of one end of an arm rest 1'7 on said rod, together with its companion washers 21 and 26 on the upper and under sides thereof and arranged in the same manner as that indicated for the rear edge of the seat 14. Sleeves 25 and washers 21 are then alternately positioned on the rod 37, with the annular hood 32 of said washers extending downwardly, as shown in Fig. 3, until the required height of the back standards has been attained.

At convenient heights on each of the back standards 15, one of the sleeves 25 is provided with a longitudinal slot 38 which is cut completely through the wall of said sleeve and, for purpose of illustration, these particular sleeves have been designated as the uppermost sleeves in Fig. 3. Prior to the placing of the slotted sleeve 1 5 39 on the rod 3'7, one end of a back rest 16, which may be simply a flat piece of material, preferably slightly flexible, is attached to the rod 3'7, said end being curled as at 40 (see Fig. 2) to provide an attaching sleeve for this purpose. 39 is then mounted on the rod 3'7 with the slot 38 providing clearance for the back rest 16, after which a plain washer 41 with a depressed central portion 42 for engagement with the upper end of the curled portion 40 on the back rest 16, is placed on the rod 3'7 and then a nut 43 is threaded on the upper end of the rod 37 and tightened against the lower nut 44 to securely position the several assembled parts on said rod. The washer 21 is then placed on the rod 37 above the nut 43 for concealment and a finishing nut 36 is threaded on said rod above said washer, with a similar nut on the lower end of said rod for contact with the floor. When positioned, the upper end of the curled sleeve portion 40 abuts against the depressed part 42 of the washer 41 and the lower end of said sleeve portion seats against the basev of the adjacent washer 21.

At the forward end of each armrest 1'7, the support 18 therefor comprises a central rod 45 which is threaded at its opposite ends. The lower end of said rod passes through a hole 46 provided in the seat 14 and has secured to the end thereof a nut 4'7 which is housed within a recess 48 provided on the underside of said seat. On the upper side of said seat, washers 26 and 21- are successively slipped on the rod 45 and moved downwardly until they contact with said upper side, with the annular flange 30 of the washer 26 abutting against said seat and the washer'21 serving as a concealment for saidlast named washer and also as a seat for the reception of the lower end of'a tubular sleeve 25 which is next placed on the rod 45. Washers 21 and 26 are'then successively positioned on the rod 45 in inverted positions from those placed on the lower end of said rod, with the annular flange 30 of the washer 26 seating against the underside of the forward end of the arm-support 17 which is provided with a hole 49 for the passage there- The sleeve through of the rod 45,- A plain washer to is then placed upon the rod 45 for contact with the upper eral parts of-the support 18 in position against the lower nut 47. A washer 21 is then placed on the rod 45 to conceal the nut 51 and the washer 50, after which a finishing nut 36 is threaded on said rod, thus completing-the assembly of the entire chair.

As regards the strength qualifications of the article offurnitureabove described, it will be observed that where asingle washer 21 is interposed between a pair of sleeves 25, the opposed end edges of said sleeves are seated on flat surfaces and in substantial alignment with each other. This alignment is maintained by the provision of 'theannular shoulders 23 and 24 which positively prevent-anytendency of the sleeves to engage in a lateral movement. The purpose of the washers 26 is to prevent any tendency of the washers 21 to flatten out under load conditions or under the application of the tightening strain as produced by the nuts 20and v35, 43 and 44, or 47 and 51, the annular wall 29 of said washer being in substantial. alignment with the walls of the tubular sleeve. 25; so that the load is transmitted in straight lines'in substantially the same manner as though the several washers 26 were continuations, or extensions, of the sleeves 25. This strength characteristic of the washers 26 is further enhanced by the provision of the annular flange 30 which serves todistribute the load carried thereby over, the relatively broad surfaces with which said flanges contact. However, it is contemplated that the washer 26 may be eliminated, merely by increasing the thickness'of the section of the washers 21, this modification in the construction being shown in Fig. 5.

Due to the fact that the chair is fabricated of a number of small pieces which are held in position by primary, securing parts which, comparatively speaking, are remotely disposed from each other, enables the parts of which the chair is composed to give slightly under load conditions, with a corresponding increase in the comfort obtainable over chairs formed of rigid members. This flexible characteristic is deemed to be one of the most important advantages of this type of construction. It will be particularly observed that the chair, or any other article of furniture constructed 'in the same manner, may be assembled without the use of glue or the agencies now common in the industry and that it may also be easily and quickly assembled by unskilled labor.

While I have shown one set of elements and combinations thereof for effectuating my improved article of furniture, it will be understood that the same is intended for purpose of illustration only and in nowise to restrict my device to the exact forms and structures shown, for many changes may be made therein without departing from the spirit of my invention.
